Row wise insertion of Master - Child Record
Hi,
Please help me with below scenario:
I have two tables Master - M and child - C
M Contains M1, M2,
C Contains M1 C1, M1 C2, M2 C3
Currently the ODI inserts data of Table M and then it inserts data of C
But I want the data to be inserted in the below given format
1. M1 should be inserted
2. Then C1, C2 to be inserted, if there is any error while inserting C2, ODI should rollback C2, C1 and also M1.
3. Then it should start with next row of the Master table, and if there is no error while inserting the master and child record, then records M2 and C3 should be commited.
Thanks in advance.

Hi Varma,
I also need the steps for the same scenario. Cezar have given me some work arounds, which is working fine(row by row transformation) but we are facing some problem in commit and rollback. The steps are given in the below link.
Commit Rollback for Parent & Child table
Thanks in Advance,

Insert new Master Data Record for an InfoObject using a Function Module
Hi @ all,
is there any Function Module for creating a new master data record for an InfoObject? Implementing a FM for inserting a master data record into a master data table is done quickly. I think there will be problems with inconsistency implementing a FM using a simple "Insert" Statement. Isn´t it?
I know it is possible to maintain an InfoObject in RSA1 (Master data IO> right click>Maintain Master data>execute(F8)> ...) but I have another requirement for using a FM.
Thanks!

Odi-row wise insertion of single source into multiple interfaces in package
hi,
i have an issue.My source table is emp(empno(pk),name,job,mgr,sal,deptno,comm).And my target tables are
emp1(name,empnoa(pk),deptno),emp2(empnob(pk),job,sal).
i have two interfaces: interface1----emp to emp1
interface2-----emp to emp2.
I have 100 rows in my source table.
Requirement is :in my package i put interface 1 after interface 2.
For each row of the sorce emp.The data should go into targets emp1,emp2.If a particular row isnt getting into either emp1 or emp2.That particular should rollback[i.e it should enter into either emp1 or emp2].
The insertion should be row wise and not the whole of source data.
How do i go about this?Perhaps this will work:
Keep interface 1 as is - run it first in the package.
for interface 2, join emp to emp1, only update/insert into target (emp2) if: emp.empno = emp1.empnoa - this way, you will not add anything to emp2 that is not in emp1.
then, create a simple procedure to
delete *
from emp1
where not empnoa in (select empnob from emp2)
They may be a better solution, but this is easy and should work just fine. -
"Failed to validate all rows" when inserting in master detail scenario
Hi,
I have problem writing data in a master detail scenario..
i use the following bean method to write data.
Data is inserted in the master table successfully but when i try to commit in the details table i get the error "Failed to validate all rows in a transaction."
public void save(ActionEvent actionEvent)
//writing into master table
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterBind =
(DCIteratorBinding)bindings.get("Master1Iterator");
MasterVOImpl vo_pr = (MasterVOImpl ) iterBind.getViewObject();
Row r=vo_pr.createRow();
r.setAttribute("Name", name);
Number num =(new oracle.jbo.server.SequenceImpl("new_seq",vo_pr.getDBTransaction())).getSequenceNumber();
r.setAttribute("Id",num);
vo_pr.insertRow(r);
vo_pr.getDBTransaction().commit();
//writing into details table
DCIteratorBinding scopeiterBind =
(DCIteratorBinding)bindings.get("Detail2Iterator");
DetailVOImpl vo_sc = (DetailVOImpl) scopeiterBind.getViewObject();
Row rs=vo_sc.createRow();
rs.setAttribute("iddetail",iddetail);
rs.setAttribute("Name", Name);
rs.setAttribute("id",num);
vo_sc.insertRow(rs);
vo_sc.getDBTransaction().commit();
Note: the Detail iterator used here is the one under the master in the AMIn case your model defined a view link from master to detail should try to get the detail iterator from the master and use this to create the new row.
Row r=vo_pr.createRow();
r.setAttribute("Name", name);
Number num =(new oracle.jbo.server.SequenceImpl("new_seq",vo_pr.getDBTransaction())).getSequenceNumber();
r.setAttribute("Id",num);
vo_pr.insertRow(r);
// this method gets the detail iterator for the master row you just created.
// The name of the method depends on the view link in your model you expose to the master view
Row rs=vo_pr.getDetail().createRow();
rs.setAttribute("iddetail",iddetail);
rs.setAttribute("Name", Name);
// this value should be added by the framework
//rs.setAttribute("id",num);
vo_sc.insertRow(rs);
vo_pr.getDBTransaction().commit();Timo -
ADF BC : Problem in Inserting a Master - Detail Record
Hi,
I am new to ADF Business Components. I am into a project where i use only the ADF BC as ORM/DB Operations and for the front end I use some other framework. The Problem is.
I have two entity objects and a ViewLink between them. [Relation between "Order" to "Item" is (1 to many relation)].
[I saw many examples in forums where its explained with View Objects But here I DID NOT create any View Object. I have only Entity Objects]
(1) OrderEO [Entity Object for Order Table]
(2) ItemEO [Entity Object for Items Table]
(3) OrderItemsViewLink [A Viewlink where OrderEO.OrderId = ItemEO.OrderId]
All The Primary keys (for the "Order" and "Items" table ) are handled by Trigger+Sequence at the time of insert in DB side.
I created custom method to insert "Order" individually it worked fine.
I created custom method to insert the "Item" individually it worked fine.
But...
When I created and "Order" with some "Items" It failing to insert and throws an
Error : oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity: detail entity ItemEO, row key oracle.jbo.Key[0 ].
My Custom Method in the AppModuleImpl is like below :
public void createNewOrderWithNewItems() {
String entityName = "com.proj.entities.OrderEO";
EntityDefImpl orderDef = EntityDefImpl.findDefObject(entityName);
OrderEOImpl newOrder = (OrderEOImpl)orderDef .createInstance2(getDBTransaction(),null);
try {
// 3. Set attribute values
newOrder .setOrderStatusCode("CREATED");
RowIterator items = newOrder .getItemEO();
Row newItemRow = items .createAndInitRow(null);
items .insertRow(newItemRow );
newItemRow .setAttribute("itemDate", new Date());
newItemRow .setAttribute("itemQty", new Number(10));
// 4. Commit the transaction
getDBTransaction().commit();
} catch (SQLException e) {
e.printStackTrace();
} catch (JboException ex) {
getDBTransaction().rollback();
throw ex;
Here the "Order" is also new and related Items is also new. What I expect is to save the Order with Items in one transaction. How to achieve this. Please suggest.
Thanks
Narayan

I have a tabular model that has States (StateID, StateName)
Then I have Cities (CityID, StateID,CityName)
Employees(EmpID, CityID, Login ID)
When I then go and setup a row filter so that my Employees table filters on their windows login name so they only see a few CITYIDs per employee.
=Cities[CityID]=LOOKUPVALUE(Employees[CityID],Employees[Login Id],USERNAME(),Employees[CityID],Cities[CityID])
The table Cities is related to States via PK States[StateID] and FK Cities[StateID] (so the arrow goes from Cities and points to States)
What gets odd here is that when I connect with a user who only has cities in 2 states, I see OTHER states for which that user has no cities.
I don't understand that. If they have Cities of Des Moines (Iowa) and Madison (Wisconsin) why are they seeing any states other than those two states?
The user sees ONLY the cities they are supposed to...why are they seeing States that aren't related to their cities?Hi,
The DAX formula you posted was fine. Have you define the relationship between "Employees" and "Cities" tables(Employees->Cities)?
Please go through the following articles regarding implement dynamic security by using row filters, maybe we have missed anything:

Insert child record when user commit parent data
Hi everybody,
My use case is an admin users page, where users add new users to application. So they specify user_name, last_name, .....
I'd need to insert in a child record whose FK is user_name which was introduced by user in the parent table, just in the commit stage.
How can I achive it? I'm user Jdev 12.1.2
Regards,
Jose.well leave that example...
How you commiting the first row.. are using commit operation.Commit in bean using java code like this.
public static OperationBinding findOperation(String operationName) {
OperationBinding op = getDCBindingContainer().getOperationBinding("Commit");
if (op == null) {
throw new RuntimeException("Operation '" + operationName +"' not found");
return op;
. and after this you can get instance of vo of second VO. then create row
ViewObjectImpl demo1 = am.getEmployeesDemo1();
Row r2 = demo1.createRow(); // Creates a row in ViewObject
r2.setAttribute("EmployeeId", 001); // you can set all values
demo1.insertRow(r2); //Insert that row in ViewObject
am.getDBTransaction().commit(); //Commit the changes
demo1.executeQuery(); -
I have a master table and i need to import the rows into the parent and child table.
Master table name is Flatfile_Inventory
Parent Table name is INVENTORY
Child Tables name are INVENTORY_AMOUNT,INVENTORY_DETAILS,INVENTORY_VEHICLE,
Error details will be goes to LOG_INVENTORY_ERROR
I have 4 duplicate rows in the Flatfile_Inventory which i have already inserted in the Parent and child table.
Again when i run the query using stored procedure,
its tells that all the 4 rows are duplicate and will move to the Log_Inventory_Error.
I need is if i have the duplicate rows in the flatfile_Inventory when i start inserting into the parent and child table the already inserted row have the unique ID i
must identify it and delete that row in the both parent and chlid table.And latest row must get inserted into the Parent and child table from Flatfile_Inventory.
Please help me to write the query i have attached the Full stored procedure Script..

Master Child tables how to get the latest rows from both
Hi,
Need some help with the sql. I have two tables Master & Child. In my Master table I have multiple rows for the same record and in the child table also multiple rows for the same master row how can I get the latest one's from both.
For example Data in my Master table looks like
CONT_ID SEQ_NUM DESCRIPTION
1 189 Update 2
1 188 Update 1
1 187 NewNow in the child table for the same CONT_ID I may have the following rows
CONT_ID UPDATED_DATE STATUS
1 3/16/2010 2:19:01.552700 PM P
1 3/16/2010 12:29:01.552700 PM A
1 3/16/2010 12:29:01.552700 PM P
1 3/16/2010 12:19:01.552700 PM NIn my final query how can I get the row with seq_num 189 as it's the latest in Master table and from child table the row with status of P as it's the latest one based on the time. Here is the query i have but it returns the latest row from the child table only and basically repeats the master table rows as opposed to one row that is latest from both:
ThanksHi,
You can use the analytic ROW_NUMKBER function to find the latest row for each cont_id in each table:
WITH got_m_rnum AS
SELECT cont_id, seq_num, description
, ROW_NUMBER () OVER ( PARTITION BY cont_id
ORDER BY seq_num DESC
) AS m_rnum
FROM master_table
-- WHERE ... -- any filtering goes here
, got_c_rnum AS
SELECT cont_id, updated_date, status
, ROW_NUMBER () OVER ( PARTITION BY cont_id
ORDER BY updated_date DESC
) AS c_rnum
FROM child_table
-- WHERE ... -- any filtering goes here
SELECT m.cont_id, m.seq_num, m.description
, c.updated_date, c.status
FROM got_m_rnum m
JOIN got_c_rnum c ON m.cont_id = c.cont_id
AND m.m_rnum = c.c_rnum
AND m.m_rnum = 1
;If you'd like to post CREATE TABLE and INSERT statements for the sample data, then I could test this.
If there happens to be a tie for the latest row (say, there are only two rows in the child_table with a certain cont_id, and both have exactly the same updated_date), then this query will arbitrarily choose one of them as the latest. -
BC4J - Inserting Master/Detail records in same transaction.
I know this is possible, but I seem to be missing something to allow it to happen within BC4J.
I'm creating a RowSet off of a View Object and inserting new Rows into this RowSet. This RowSet represents my child/detail records for insert into a child table.
I then create a new Row off of another View Object. This row represents my Master/parent record for insert into a parent table.
All of the above is being done in the same applicationModule transaction with locking mode set to Optimistic.
Before I commit the transaction, I grab the next sequence # to use as the primary key for the master record and the foreign key for the child records. I apply those to the newly created child rows and the newly created master row.
However, when I commit I continue to get a JBO-26041: Failed to post data to database during "Insert": error due to ORA-02291: integrity constraint (CUST_LICENSES_FK4) violated - parent key not found
If everything was created in the same transaction, why won't this allow me to insert into both tables with the correct primary/foreign keys? It's almost as if the child records are being inserted first prior to the parent record.
Any ideas?
Thanks in advance..

[email protected]However, when I commit I continue to get a JBO-26041: Failed to post data to database during "Insert": error due to ORA-02291: integrity constraint (CUST_LICENSES_FK4) violated - parent key not found
If everything was created in the same transaction, why won't this allow me to insert into both tables with the correct primary/foreign keys? It's almost as if the child records are being inserted first prior to the parent record.This is due to the order of rows being posted. In this case it seems the detail row is getting posted before the master.
To avoid such situations, either you may implement your own post ordering by making sure that when a detail is to
be inserted, it's master is inserted or you may use "Composition Association" flag in the association wizard between
the master and the detail entities to let the framework manage a tight composition relationship between the two entity
types. BTW, there was another definitive thread recently on inserting master-detail in the
same transaction, but the forum search engine is so useless I can't find it. Anyone
have the msgid handy or know how to find that thread again??
FYI: the help describes the Composition flag functionality in terms of the Master record already existing in the DB. In our problem here, the Master is being inserted in the same transaction. Thus needs to be posted FIRST.
I got a integrity constraint exception too, then set the composition flag and now I get:

How to create Child record at the time of master record creation.
Hi,
I have MasterVO and ChildVO. And association between both are 1 to *. I have a requirement like, I need to create row in ChildVO at the time of MasterVO row creation.
I have used entity based association to create view link. This view link created ChildVO accessor in MasterRowImpl as type RowIterator.
Actually my idea is to override create method in MasterVORowImpl and call ChildVO ViewObject and call .createRow() method on it. But I don't have access to ViewObject, instead it gave access to RowIterator.
Could you please provide any pointer to achieve above functionality?
Many thanks in advance.
Jdev version - 11.1.1.7.0
Regards,
Dileep.Hi Tim,
Now it is creating child record at the time of master row creation. But it is working only through BC tester. But when I drag the child VO instance in the jsff page, only master is get created as editable only, child is displayed as read only without populating any default values like child VO surrogate key and other default attributes. But through BC tester it is working fine.
Am I missing anything here while implementing in UI?
Thanks,
Dileep. -
Inserting parent /child records from a xml file ...
XML file pasted below:
I have loaded the xml file into a table called xml_demo which has a column xml_data of type xmltype.
The select for parent record is as follows and it works:
INSERT INTO balit_submissions (balitdoc, documentversion, datetime_from,job_id, status,creation_datetime)
(SELECT 'MOL'
,to_number(extract(x.xml_data,'/MolDocument/DocumentVersion/@v'))
,to_date(substr(extract(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),
'yyyy-mm-dd"T"hh24:mi')
,123456
,'CREATED',
NULL
FROM xml_DEMO x WHERE
existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1)
Having problem creating child records. From this file I expect to create 3 records.
insert into balit_energy_blocks
SO_ID,
DATETIME_FROM,
DIRECTION,
BLOCK_NUMBER,
ENERGY,
LAST_SUBMIT_DATETIME,
PRICE_POUNDS,
PRICE_EUROS,
BALIT_REF,
STATUS,
LAST_EDIT_DATETIME,
MOL_REASON,
ACQUIRING_SO_AREA)
(SELECT 'RTE'
,to_date(substr(extract(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),
'yyyy-mm-dd"T"hh24:mi')
,DECODE(extract(x.xml_data,'/MolDocument/MolTimeSeries/Direction/@v'),'AO1','Up','Down')
,to_number(substr(extract(x.xml_data,'/MolDocument/MolTimeSeries/ContractIdentification/@v'),19))
,to_number(extract(x.xml_data,'/MolDocument/MolTimeSeries/Period/Interval/EnergyPrice/@v'))
,sysdate
,null -- price pounds
,null -- price euro
,extract(x.xml_data,'/MolDocument/MolTimeSeries/ContractIdentification/@v')
,'SUBMITTED'
,'A96'
,NULL -- acquiring area
,sysdate
FROM xml_DEMO x WHERE
existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1)
For example, there are 3 ContractIdentification tags. Example of 1:
<ContractIdentification v="RTE_20100331_1500_16"/>
I was expecting this select to pluck the last number from this string. In this case 16.
The select was:
to_number(substr(extract(x.xml_data,'/MolDocument/MolTimeSeries/ContractIdentification/@v'),19))
The result I got was:
16RTE_20100331_1500_20NG_20100331_1500_6
All contractident values are concatnated and returns from position 19 onwards.
Can anyone help me to extract the last number from each ContractIdentification tag value and to create the 3 records
Thanks
James Sathiaraj

</MolDocument>Hi,
The result I got was:
16RTE_20100331_1500_20NG_20100331_1500_6In the query you tried, you access a single record so you can't expect to get three rows "magically". The EXTRACT function just works as expected, it extracts the requested nodes, but the result is still an XML fragment (a scalar value).
In order to achieve your goal, you have to break the MolTimeSeries sequence into relational rows.
Two similar solutions are possible, XMLTable (10gR2 and up) or Table/XMLSequence.
In your other post you mentioned db version 10.1, so I guess we'll go with XMLSequence :
SELECT 'RTE'
,to_date(substr(extractvalue(x.xml_data,'/MolDocument/ValidTimeInterval/@v'),1,16),'yyyy-mm-dd"T"hh24:mi')
,decode(extractvalue(x2.column_value,'/MolTimeSeries/Direction/@v'),'A01','Up','Down')
,to_number(regexp_substr(extractvalue(x2.column_value,'/MolTimeSeries/ContractIdentification/@v'),'\d+$'))
,to_number(extractvalue(x2.column_value,'/MolTimeSeries/Period/Interval/EnergyPrice/@v'))
,sysdate
,null
,null
,extractvalue(x2.column_value,'/MolTimeSeries/ContractIdentification/@v')
,'SUBMITTED'
,'A96'
,null
,sysdate
FROM xml_demo x,
table(
xmlsequence(
extract(x.xml_data, '/MolDocument/MolTimeSeries')
) x2
WHERE existsnode(x.xml_data,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1;Please also note the use of REGEXP_SUBSTR instead of the regular SUBSTR because it didn't work for "NG_20100331_1500_6".
Hope that helps.

Deleting rows with child records
Hi,
I want to delete some records from master table based on where condition. But I want all the corresponding child record should also delete from the respective child tables..
Can anyone tell me how to go about it with example( eg emp & dept table of scotts)
RegardsI have been to slow for posting...
Please note that I hate doing this
SCOTT@LSC01> select count(*) from emp;
COUNT(*)
14
SCOTT@LSC01> delete dept where deptno=10;
<font color=red>1 row deleted.</font>
SCOTT@LSC01> select count(*) from emp;
COUNT(*)
11the risk is that someone is not aware of deleting rows, and instead of getting
SCOTT@LSC01> delete dept where deptno=10;
delete dept where deptno=10
ERROR at line 1:
ORA-02292: integrity constraint (SCOTT.FK_DEPTNO) violated - child record foundhe is deleting rows in other tables and will never be aware of that deletion ... -
Child Records getting inserted before Parent
HI All,
I have an Entity object (Vendors) that has a defined relationship to payments (12 months) when I create a new vendor record I'm creating the 12 child records that all works fine but when I try to issue a commit the child records get inserted first creating a constraint error. If I turn the constraint off and using the "Jbo.debugoutput=console" I can see the 12 months being inserted followed by the vendor record. The payment records vendor_id is being set to the correct parent but the insert is happing in the wrong order does anybody know how to control the order of the insert. There's a Association set between the Vendor entity and the payment entity. If I move the code to a view object it seems to work fine. But in this case we have multiply view objects on these entity objects and I'm trying to prevent having to write the same code in every view Object.
Here's the code for the Create on the Vendors EntityImpl
protected void create(AttributeList attributeList) {
super.create(attributeList);
// Set the default values and the Seq number for this new record
SequenceImpl seqNoImpl = new SequenceImpl("VENDORS_SEQ",getDBTransaction());
this.setVendorId( seqNoImpl.getSequenceNumber());
Number zeroAmt = new Number(0);
RowIterator paymentsIter = this.getVendorPayments();
// When creating a new Vendor create the 12 months of payment records
for (int i = 1; i < 13; i++) {
Row newRow = paymentsIter.createRow();
newRow.setAttribute("Month",i);
newRow.setAttribute("Amount",zeroAmt);
paymentsIter.insertRow(newRow);
Dose anybody have any ideas....Pieter,
Thanks for the information!!
Using it I was able to get the process working. There where some interesting side affects. If I just turned on the "Composition Association" then no payment records got inserted into the database even though they where in the entity and view objects. I took the second recommendation of adding code to the PostChanges event and was able to get the parent and children inserted in the correct order.
Thanks again for the idea and information -
Get all records in multi selected master child tables
Hi,
I am using JDeveloper 11.1.1.4 version and using ADF-BC in my project.
I have a simple master child[one to many] relationship in my project.
In my view page,I display this master child [Ex: EmpVo1--->DeptVo2] as tables.
I have multi-slection enabled for master table.
My requirement is that,on multi selecting the rows in master tables,I want to get all the child records in my backing bean.
that is if a master row has 3 child records and another master row has 4 child records and on multiple selection of these two records in master table,I should get all the child records in my backing bean.
I need this to implement cascade delete functionality.
Following is sample piece of code
1) called on selecting the rows in master table
public void onRSCGrpSelect(SelectionEvent selectionEvent) {
// Add event code here...
ADFUtil.invokeEL("#{bindings.RscGroupVO1.collectionModel.makeCurrent}",
new Class[] { SelectionEvent.class },
new Object[] { selectionEvent });
RowKeySet rowKeySet = (RowKeySet)tblRSCGrp.getSelectedRowKeys();
CollectionModel cm = (CollectionModel)tblRSCGrp.getValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData =
(JUCtrlHierNodeBinding)cm.getRowData();
Row row = rowData.getRow();
System.out.println("\n" +
row.getAttribute(0) + " :: " + row.getAttribute(1) +
" :: " + row.getAttribute(2));
System.out.println("Displaying Child Records");
displayChildRecords(row.getAttribute(0));
2. private void displayChildRecords(Object rscGrp) {
ViewObject rscMapVo = getRscMapViewObj();
RowSetIterator rsI = rscMapVo.createRowSetIterator(null);
while (rsI.hasNext()) {
Row row = rsI.next();
System.out.println("\n" +
row.getAttribute(0) + " :: " + row.getAttribute(1) +
" :: " + row.getAttribute(2));
rsI.closeRowSetIterator();
But the problem is that ,it is always giving me the last selected rows child record details
Please suggest the error I am doing.
Thanks,
PraveenYour problem is that you use makecurrent, which should not be used on a multi select table. Next if you have master detail relationship you should have a view link between them. In this case you can expose a method in you master to get the related child row. No need to get the VO itself as you can use the child iterator accessors to get the child record.
public void onRSCGrpSelect(SelectionEvent selectionEvent) {
// Add event code here...
RowKeySet rowKeySet = (RowKeySet)tblRSCGrp.getSelectedRowKeys();
CollectionModel cm = (CollectionModel)tblRSCGrp.getValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData =
(JUCtrlHierNodeBinding)cm.getRowData();
Row row = rowData.getRow();
//cast to the right row class
EmpEmpVoRow empRow = (EmpEmpVoRow) row;
// now you cann access the child row iterator
RowSetIterator it = empRow.getDepVO();
//now you cna iterate over the child rows
System.out.println("\n" +
row.getAttribute(0) + " :: " + row.getAttribute(1) +
" :: " + row.getAttribute(2));
System.out.println("Displaying Child Records");
//use hte child rows here
}Not sure if the code compiles out of the box (doing this on the train :-)
